Should frontend and backend be handled by different controllers?

Question

In my previous learning projects I always used a single controller, but now I wonder if that is good practice or even always possible.

In all RESTful Rails tutorials the

Answer 1

Use two current if there are two modules 1] Admin 2] User

Say

class BookUserController < ApplicationController
  #Here layout is used will be of layouts/application.html.erb
  #Here all the methods which user can will be present 
end


class BookAdminController < ApplicationController
  layout 'admin'  #here we set the layout is layouts/admin.html.erb 

end

IF Only one page you want to show admin you can use single controller and two methods

class BookUserController < ApplicationController
  layout 'admin', :only=>['index_admin']

  def index_admin


  end

  def index



  end


end

OR

class BookUserController < ApplicationController
  def index_admin

    render :action=>'index_admin', :layout => false
  end

  def index



  end


end
